Plugged code reader in obd port says pcm has problems
Dodge Ram 3500 2014 6.7L Cummins 200000 miles
Checked fuse for Pcm not getting any power to the pcm
OBDII Scanner unable to "Communicate with PCM"
Dodge Ram 3500 2004 SLT, 5.9L TC Diesel, 3500 215000 miles
The On-board diagnostics (OBD) scanner will power on, but will not "Communicate with the PCM." The engine is running great, with no misfiring or stutter. No engine codes are being thrown either. All fuses are operating and not blown.

Drain batterys remove iod fues batterys holding charge need help also RPM to hight
My opinion is that Dodge does this on purpose. They want you to pay at the dealership. They will give you a printout of all the codes, but these generic OBD2 plug in scanners "do not communicate with PCM" by design $$
